Libec Extendable jib arm with carrying case

The standalone Libec Extendable Jib Arm with Carrying Case (predominantly known in production environments as the Libec JB50 Standalone Package) is a premium, portable telescopic mini-jib engineered to execute smooth vertical, horizontal, and multi-axis diagonal crane movements.

Rather than relying on fixed-length, bolt-on extension segments that are time-consuming to assemble in the field, this system integrates high-compression mechanical lock levers that let a single operator adjust the arm's reach instantly.

Core Design & Technical Capabilities

1. Lever-Lock Telescopic Range

The defining mechanical feature of the jib is its telescoping front arm. By simply flipping the integrated clamp levers, you can continuously scale the operational front arm length anywhere from 100.0 cm to 190.0 cm (39.5" to 75.0"). This lets crews instantly adapt to tight indoor studio sets or slide the arm out to its limit for expansive, high-angle outdoor sweeping shots.

2. Dynamic Weight Capacity Calibration

The internal structural architecture is engineered to manage high payloads that scale based on your extension distance.

• At its shortest configuration (100.0 cm), it acts as a rigid, ultra-stable stub arm capable of hoisting full cinema camera arrays or remote pan/tilt heads weighing up to 20.0 kg (44.0 lbs).

• At its maximum extended length (190.0 cm), it retains a highly capable 10.0 kg (22.0 lbs) payload capacity, matching or exceeding what many traditional fixed-length modular jibs can handle at half that distance.

3. Compact Rear Retraction & Balancing

Using the included hex wrench, the entire central support column can slide back by 30.0 cm (12.0") toward the rear counterweight section. This adjustment is critical when working in small rooms or near walls, allowing you to compress the rear swing radius so the back of the jib doesn't hit obstacles during wide panning movements.

4. Universal Head Mounting Base

The base features a standard 100mm half-ball/bowl interface designed to mount directly onto industry-standard heavy-duty video tripods. The front camera mounting platform is a 100mm bowl that includes a premium 75mm adapter ring mount, allowing you to attach a wide range of compact or mid-sized fluid video heads right out of the box.

Operational System Tips for the Extendable Jib:

💡 The Low-Angle Reversible Trick: The front camera mounting platform is entirely reversible. If you need to execute ultra-low, ground-hugging tracking shots where a standard upright fluid head sits too high, you can unbolt and invert the front platform to operate in an underslung orientation. Pair this layout with an inverted fluid head or a dedicated undermount adapter to safely skin the floor.

• Isolating Monitor Drag: Never mount a director’s monitor or a wireless video receiver directly onto the tilting arm tubes, as their weight distribution shifts your counterweight center of gravity when the jib tilts up or down. Instead, screw your articulating monitor arms into the 1/4"-20 and 3/8"-16 threaded mounting sockets located on the stationary central support column, keeping your monitoring screen perfectly stationary while the arm moves smoothly around it.
